In today's manufacturing world, understanding the difference between additive and subtractive manufacturing is crucial for choosing the right production method. HUIWEN has tailored both solutions to meet high standards and specific needs. Here, we will explore the differences, advantages, and applications of the two approaches.
Additive manufacturing and subtractive manufacturing: in-depth comparison and difference
1. What is rapid prototyping manufacturing?
Rapid prototyping manufacturing technology builds objects layer by layer. This process is known for its flexibility, enabling complex designs that are difficult to achieve with conventional methods. Common rapid prototyping manufacturing techniques include
3D printing: ideal for prototyping and small batch production. It can produce complex shapes without a mold.
Injection molding: Although commonly used in mass production, it also has additive properties and uses molds to precisely shape materials.
Rapid prototyping manufacturing is an excellent choice for customization. It can quickly produce unique parts, reduce waste, and is increasingly popular in industries such as aerospace, automotive, and medical.
2. What is subtractive manufacturing?
Subtractive manufacturing, as the name implies, is the removal of material from a solid block to create a desired shape. This method is suitable for high-precision components and is known for producing smooth, precise finished products. Common subtractive manufacturing techniques include
Nc milling: NC milling: NC milling uses a rotary cutting tool to remove layers from a workpiece. It is highly accurate and widely used in metal and plastic parts.
Turning: During turning, a cutting tool is used to remove material from a rotating workpiece. This method is often used for cylindrical parts such as shafts and rods.
Subtractive manufacturing is ideal for parts with strict tolerance requirements. This method is often chosen in situations where accuracy is highly required, and is therefore popular in aerospace, automotive, and industrial machinery.
3. Compare advantages and disadvantages
Both additive and subtractive manufacturing have their own unique advantages and disadvantages.
Advantages of rapid prototyping manufacturing
The flexible design is ideal for complex and customized parts.
Use only necessary materials to reduce waste.
Speed up prototyping and reduce production time for custom orders.
Disadvantages of rapid prototyping manufacturing
The low strength of some materials limits their use in structural components.
In mass production, the rate tends to be slower.
Material options are limited, especially for certain high-strength metals.
Advantages of subtractive manufacturing:
High precision, suitable for strict specifications of the components.
The solid material base makes the parts stronger and more durable.
Suitable for a variety of materials, including hard metals.
Disadvantages of subtractive manufacturing:
There is much material waste due to the need to remove excess material.
For complex designs the efficiency is less and additional steps may be required.
Due to setup requirements, the cost of small batch, highly customized production is high.
4. Choose the right manufacturing method according to the demand
The best approach depends on the specific needs of the project. If you need high-strength parts with precise tolerations, subtractive manufacturing may be a better choice. For complex custom design or rapid prototyping, rapid prototyping manufacturing is more flexible and efficient.
